摘要

The electrochemical growth of carbon nanotubes (CNTs) - conducting polymer composites offers the ability to produce three-dimensional nanostructured films that combine the redox pseudo-capacitive charge storage mechanism of conducting polymers with the high surface area and conductivity of CNTs [1 -3]. In this paper we report the electropolymerization and characterization of polypyrrole films (PPy) doped with poly (m-aminobenzenesulfonic acid) (PABS) functionalized single-walled carbon nanotubes (SWCNTs) (PPy/CNTs). The negatively charged CNTs served as anionic dopant during the electropolymerization to synthesize PPy/CNTs composite films. Electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV) and scanning electron microscopy (SEM) were used to investigate the electrochemical properties of the composite films.
